Display log time

[sjbitcode]

Summary

This PR adds an extra column to the rich Console output for displaying the time.

Changes

💡 In order to display a time, the logging handler needs a formatter that specifies a datefmt. This is needed so that the formatter can call formatTime, and we use that value to display!

• Have DjangoRequestHandler.__init__ set a default formatter if none is passed in, else use passed in formatter
• Have DjangoRequestHandler.emit call formatTime on its formatter and adds extra column to log output
• Adds DjangoRequestHandler.__init__ tests 🧪

Testing

1. Default formatter: Run the example project to see the default formatter at work! Time format will be HH:MM:SS
2. Custom formatter: Add one of the pre-defined formatter to the django_rich_logging handler here. Time format will be whatever the formatter's datefmt setting is.
   • For example if you add "formatter": "verbose",, the time format will be YYYY-MM-DD HH:MM:SS

Notes, Questions, & Follow-up

• Modify README to include note about optionally passing a formatter to the django_rich_logging handler
• Should the tests check for the cell content?
  • current tests does minimal checking for the Method and text color
  • time checking would require something like freezegun?
• Update gif?
